// Provide optimized functions to convert images from 8bits yuv420 to rgb24 format
|
||||
|
||||
// There are a few slightly different variations of the YCbCr color space with different parameters that
|
||||
// change the conversion matrix.
|
||||
// The three most common YCbCr color space, defined by BT.601, BT.709 and JPEG standard are implemented here.
|
||||
// See the respective standards for details
|
||||
// The matrix values used are derived from http://www.equasys.de/colorconversion.html
|
||||
|
||||
// YUV420 is stored as three separate channels, with U and V (Cb and Cr) subsampled by a 2 factor
|
||||
// For conversion from yuv to rgb, no interpolation is done, and the same UV value are used for 4 rgb pixels. This
|
||||
// is suboptimal for image quality, but by far the fastest method.
|
||||
|
||||
// For all methods, width and height should be even, if not, the last row/column of the result image won't be affected.
|
||||
// For sse methods, if the width if not divisable by 32, the last (width%32) pixels of each line won't be affected.

// is suboptimal for image quality, but by far the fastest method.
